Quaternions and back.
For all the people who always want to use them, here is a scene with two cubes.
The first cube is able to rotate. The objmatrix is connected to a script to transform the
Pitch, Roll and Yaw into quaternion matrix X,Y,Z,W. The next script in the chain transforms
it back to Pitch, Roll and Yaw.
Do what you want with these scripts.
